Important Safety Instructions
When using this treadmill, basic precautions should always
be followed, including the following:
Read all instructions before using this treadmill.
Consult your physician before beginning any exercise
program.
Danger: To reduce the risk of electric shock, always unplug
this treadmill immediately after use and before cleaning.
Warning: to reduce the risk of burns, fire and electric shock
and injury to persons:
This treadmill should never be left unattended when plugged
in. Unplug it from the outlet when not in use and before any
service is performed.
Close supervision is necessary when this treadmill is being
used by or near children, invalids, or disabled persons.
Use this treadmill only for its intended use as described in
this manual.
Do not use attachments not recommended by the
manufacturer.
Never operate this treadmill if it has a damaged power cord
or plug, if it is not working properly, if it has been damaged
or dropped, or if it has been submerged in water. In these
cases, the treadmill should be examined by a qualified service
technician.
Use a dedicated 110 volt, alternating current (AC), 15 amp
three-prong grounded outlet.
Safety Instructions
2
Keep the power cord away from heated surfaces.
Never drop or insert any object into any opening.
To disconnect, turn the power switch to the OFF position,
then remove the plug from the outlet.
Do not allow animals on or near your treadmill.
Make sure the power cord has enough slack to allow the
treadmill to raise freely without being limited by the cord or
caught in the incline rack. Do not run the power cord under
treadmill.
Use the treadmill indoors only.
Never use your treadmill near water or while wet. Using the
treadmill around a pool, hot tub or sauna will void the
warranty.
Do not operate where aerosol (spray) products are being used
or where oxygen is being administered.
Allow only trained personnel to service this equipment.
Keep the area under the treadmill free from obstruction, as
the deck will return to 0% grade when the safety key is
placed on console.
Avoid the possibility of bystanders being struck or caught
between moving parts by making sure that they are out of
reach of the treadmill while it is in motion.
Keep the space behind and on both sides of the treadmill
clear should you lose your balance.
Setting Up Your Treadmill
3
Allow only one person at a time on your machine.
Do not operate treadmill without the safety key attached to
the console and the lanyard clipped to your clothing at
approximately waist height.
Always straddle the treadbelt and allow the belt to begin
moving before stepping onto the belt.
Use extreme caution when stepping onto moving tread belt.
Some programs begin at speeds as high as 4.8 mph.
Gradually slow down the belt before stopping. This will
minimize the sensation of movement after you stop.
When making treadbelt adjustments, keep fingers, loose
clothing, jewelry, and long hair away from moving parts.
Setting Up Your Treadmill
Place your treadmill on a clean, level surface. Make sure the
electrical cord easily reaches a grounded three-pronged outlet
and has enough slack to allow the deck to incline without
tightening the cord. Do not allow the treadmill assembly to
rest on the cord.
Although your treadmill is designed to operate on most
carpeted surfaces, some deeply padded or heavy shag carpets
can cause damage. To prevent damage to your treadmill or
carpet, have someone stand on the deck and make sure the
treadmill belt doesn’t touch the carpet at any point.
Your treadmill is designed for indoor use only. Always keep
the control panel out of direct sunlight.
Setting Up Your Treadmill

Important Electrical Requirements
Your True treadmill requires a dedicated 110 volt,
alternating current (AC), 15 amp grounded outlet circuit.
This means nothing else can be plugged into the same power
circuit. Most power circuits are rated for this 110VAC 15-amp
requirement, but you must ensure the
treadmill does not share the circuit with anything else.
Danger: Do not use an extension cord or an ungrounded
outlet. The ground helps prevent electrical damage to your
treadmill and enhances your safety by preventing shock.
Check with a qualified electrician or serviceman if you are in
doubt as to whether the treadmill is properly grounded. Do
not modify the plug provided with the treadmill – if it will
not fit the outlet, have a proper outlet installed by a qualified
electrician.
A grounded outlet is critical for the Heart Rate Control
system to function properly.

Treadbelt Adjustment
Your treadmill’s running belt has been properly aligned at
the factory. However, when the treadmill is used on an
uneven surface, please follow these instructions:
Treadbelt Adjustment
8
1. Stand beside the treadmill, place the safety key onto the
control panel and follow operating instructions for running
the treadmill at 5 mph.
2. If the belt is off-center to the right, turn the left roller
adjustment bolt counter clock-wise 1/4 turn. If the belt is
off-center to the left, turn the left roller adjustment bolt 1/4
turn clockwise.
3. Let the machine run for several minutes to check the
alignment. (Belt alignment does not need to be perfect). If
more correction is needed, turn the adjustment bolt 1/4 turn
and check again.
Treadbelt Tension
To assure maximum life of the treadbelt, roller and drive
motor, make sure the treadbelt tension is set correctly. (Your
treadbelt has been properly tensioned at the factory.)
Turn both rear roller adjustment bolts counter-clockwise
until treadbelt just begins slipping when walking on it, then
turn both rear roller adjustment bolts clockwise in equal
quarter turn increments until treadbelt stops slipping.
Note: Be sure to run on treadbelt to ensure that the
treadbelt does not slip while under load.

Basic Treadmill Operation
Basic Treadmill Operation
Starting Your Treadmill Safely
Straddle the treadbelt by placing your feet on the straddle
covers.
Attach the lanyard to your clothing at about waist height.
Place the safety key on the key holder on the console.
Set your weight using the keys and press .

Setting Your Weight
Your body weight must be entered so that the treadmill
accurately estimates your calorie expenditure. This weight
must include your workout clothing, too, which typically
adds about three pounds. The treadmill will work fine
without your weight setting, but will be unable to calculate
your calories. When you are setting your weight, it is
displayed in the Time Window.
Your treadmill will remember the last weight you entered.
Basic Treadmill Operation
11
A Note About Calorie Expenditure Calculations
True treadmills use the calorie expenditure formula as
described in Guidelines for Exercise Testing and Prescription
from the American College of Sports Medicine. This is the
most widely accepted formula for running and walking.
Due to variations in human exercise efficiency, your actual
calorie expenditure may vary by as much as 10% from the
treadmill’s estimate.
Monitoring Your Heart Rate (HRC model only)
The Z6 Series treadmill can monitor your heart rate when you
wear the transmitter strap provided. It will display it as a
digital beats-per-minute (bpm) readout, and it is very
accurate, typically within two beats per minute. Your heart
rate is good feedback on your effort level. See the Target
Heart Rate chart on page 29 for more information.
Although your treadmill functions fine without using the
heart rate monitoring feature, this kind of monitoring gives
you valuable feedback on your effort level. It also allows you
to use the most advanced training system available on a
treadmill: True’s Heart Rate Control, where the treadmill
automatically adjusts your workout level based on your heart
rate. See the Heart Rate Control section of this manual for
details.
Using the Heart Rate Transmitter
Strap
The transmitter strap should be
worn directly against your skin,
about one inch below the pectoral
muscles/breast line.
Quick Reference Operating Instructions
12
Women should be careful to place the transmitter below their
bra line.
Some moisture is necessary between the strap and your skin.
Sweat from your exercise works best, but ordinary tap water
may be used prior to your workout if desired.
The Treadmill’s Heart Rate Display
Before you start your workout, as you stand on or near the
treadmill, you will know the treadmill is properly receiving
your heart rate signal by the flashing heart-shaped “METS”
LED beneath the Heart Rate window.
Once you start your workout, your heart rate will be
displayed in beats per minute.

User Programs
During a manually-controlled workout, your Z6 Series tread-
mill always "records" the changes you make in speed or
incline. This recording can be saved as a User Program that
you can "play back" to use as custom-designed workouts.
Up to 50 changes in speed or incline can be recorded. Each
speed/incline pair of changes must be separated by at least
30 seconds.

would to end your workout. Now press and hold until
the display shows Save User 1.
You can save your workout in User 1, or press to select
User 2. Press and hold to save the workout program
you have selected.
To use a User Program that you have saved, simply select it
from the list of programs as described in "Programmed
Workouts" in the previous section.
Heart Rate Control Workout
True’s patented heart rate control workout allows you to
limit both speed and grade for your safety and comfort. The
treadmill adjusts both to keep you at your desired target
heart rate, and it remembers these setup parameters for your
next workout.
Before selecting a target heart rate control workout, it is
important to use the treadmill for several workouts in the
manual mode while monitoring your heart rate.
After you have spent some time learning how your heart
responds to different levels of speed and grade, you will have
a better understanding of how to select the maximum speed
and maximum grade required to reach your target heart rate.
Consult your physician to determine your target heart rate.
See “Heart Rate Control Important Points” for some useful
tips on using the HRC system.
How the HRC system controls your heart rate:
To raise your heart rate in the HRC mode, speed will always
increase until maximum speed is attained, followed by grade
(if grade is used in the workout).
To lower heart rate in the HRC mode, grade will always
decrease until zero grade is reached, followed by speed (if
grade is used in the workout).
Speed changes are in 0.1 mph increments. Grade changes are
in 0.5% grade increments. This is equal to between 0.10 and
0.15 METs.
NOTE: The heart rate control workout stores your workout
parameters once you have completed an HRC workout.
You do not need to enter all parameters each time you use
the HRC workout.
HRC Workout Setup
After entering weight, press . Press keys to
scroll to the HRC workout, and press .
Adjust the target heart rate to your desired target using the
, then press .
